He knows

A place in the forest

On the way there a pair of startled wings clattered up - that was all. You go alone. A tall building that consists entirely of cracks, a building that is perpetually tottering but can never collapse. The thousandfold sun floats in through the cracks. In this play of light an inverted law of gravity prevails: the house is anchored in the sky and whatever falls, falls upward. There you can turn around. There you are allowed to grieve. You can dare to face certain old truths otherwise kept packed, in storage. The roles I have, deep down, float up, hang like the dried skulls in the ancestral cabin on some out-of-the-way Melanesian islet. A childlike aura circles the gruesome trophies. So mild it is, in the forest.
